history which spans life as a family home, womenonly college, and offices. British hotel owners, Warner Leisure Hotels, has expanded and restructured elements of the site to enhance its architectural appeal and deliver luxurious spaces. A key stipulation for the £50 million renovation was to drastically reduce its carbon footprint. Chase Insulation selected Kingspan Kooltherm Pipe Insulation to insulate the pipework to help reduce primary energy use and carbon emissions. With an aged thermal conductivity as low as 0.025 W/mK (at 10°C mean), Kingspan


Kooltherm Pipe Insulation could help exceed the current energy performance requirements for Building Regulations compliance. 15,318 lm was specified in thicknesses ranging from 15 mm – 25 mm for all heating and domestic water services to work towards future proofing the hotel. The pipework supplies 200 guest rooms in the original castle and across a contemporary threestorey wing, restaurant, lounges, and a health suite within a converted stable block which includes a pool and spa.

sandstone listed building has been refitted by the property firm Dunaskin Properties Ltd to provide modern office accommodation for several local businesses. Originally built by the Victorian developer


Duncan McNaughton, it is a familiar landmark close to Glasgow Central railway station. The sixstorey building retains many of its original features including its striking façade with ornate stonework and mosaic floor tiled entrance foyer. The striking atrium that extends down to the


ground floor continues to provide plenty of natural daylight too, but the addition of LED lighting has added a more modern feel. The building also now boasts a coffee shop for the use of tenants and modernised building services, including the latest in heating technology. Three Lochinvar TTB 410 gasfired boilers


providing a total of 1.2MW of heat output were specified because of their efficiency, flexibility and ease of operation. These fully condensing, gasfired, stainless steel, floor standing boilers have low NOx emissions and can achieve efficiencies up to 95.5% gross CV. Their ability to modulate during operation


was of particular interest to the contractor G8 Energy Solutions of Hamilton. The threeboiler

modular installation offers a 24:1 turndown allowing the system to respond precisely to changes in demand while minimising energy consumption – a particularly useful feature in a building occupied by multiple tenants with long, varied working hours. The contractor also found that the boilers


were easy to manoeuvre during installation as they are relatively lightweight and are fitted with castors for ease of handling and positioning avoiding the need for lifting equipment. In addition, they feature onboard controls, twin burners for builtin standby and a highly reliable triple chamber, stainless steel heat exchanger.

heating applications and come in outputs ranging from 418 to 576 kW. According to the Baltic Chambers’


website, when the building was first opened in 1899 it featured engineering that was clearly cutting edge for the late Victorian era including “a complete system of electric lighting, besides gaspiping for fires, etc. where required”. Today, the building retains much of its


original character and charm, while the significantly upgraded heating and other modern amenities provide comfortable and productive conditions for its occupants.

an exclusive design that includes a patented woven wire gauze ‘sock’ covering the combustion head cylinder. Gas and combustion air are mixed upstream of the combustion head and then pass through precision located ports and the gauze ‘sock’ to ignite on the external surface of the combustion head. This arrangement enables a very compact flame with a diameter directly related to the burner firing rate, ensuring precise heat control and optimum efficiency at all loads. The high turndown makes RX


burners ideal for systems with variable heat loads where low NOx levels are also required. These range from condensing


boilers through to process applications such as spray booths and industrial ovens. RX burners can be used in


conjunction with variable speed drive motors to reduce electricity consumption and lower noise levels even further than the typical 30% noise reduction compared to many other combustion applications. Control options include progressive two stage operation and fully modulating via 010V or 420 mA. Full electronic control with operational and diagnostic display is also available.

Glastonbury. The logistics of putting on an event for over 200,000 people is mindboggling and ensuring the availability and accessibility of sufficient clean water is just one aspect.

Coming up with a bespoke solution to this unique requirement, Grundfos put forward a coordinated approach that involved several suggested activities. This involved the upgrade of the pump motors to more energy efficient versions, the incorporation of a new precision dosing system and a remote monitoring system that
